A new approach to detect and measure echoes in data has been formulated, which is applicable to cases where irregular sampling is concerned.

Proving the feasibility of this approach, required a significant computational effort, which would have taken a normal computer about 10 years to complete. Hive has been instrumental in finishing this project in finite time. The accompanying image shows the results of Monte Carlo simulations that benchmark the ability of the various statistical estimators considered to uncover the input lag (at 100 days). Paper has been submitted to the Astrophysical Journal.
